-Kevin asked why the median seeing value for the ecam measurements was better (smaller) than that for all of the optical instruments combined. Nancy checked with Russet after this meeting, who said "I found ecam to be reasonably representative of the visible-light instruments, a little worse than ARCTIC, comparable to Agile and NA2 guider, better than dcam.  But nowadays our visible-light log statistics are probably dominated by kcam, which does have re-imaging optics for the slitviewer that make the seeing look worse.  That could also account for the broader peak of the night-log statistics.  A quick check of the KOSMOS tab from the seeing statistics says that yes, there are only 5 sub-arcsecond log entries for KOSMOS from the whole year." +Kevin asked why the median seeing value for the ecam measurements was better (smaller) than that for all of the optical instruments combined.
